Fixed that animation was replaced by other mods who use same c_hands path

Added block animation (Defend only from melee attacks)
Added push animations (You can push away props or enemies)
Added crawling animation
Adjusted FOV
Fixed hands dissapearing (If they still do that, hit R to force the game to load animations and model)
Fixed that falling animation was playing on ladders
Clear all the code from unnecessary things.

Fixed that hand did not appear
